Plant of the Cactaceae plant family

ABSTRACT

A new and distinct plant variety of the Cactaceae family is of the type known commercially as a &#34;Christmas Cactus&#34; and has a growth habit similar to that of the &#34;Gold Charm&#34; variety but has buds and sterile flowers with somewhat different color characteristics from those of the &#34;Gold Charm&#34; variety.

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct plant variety of the Cactaceae family and which has been named the Zygocactus truncatus `Christmas Flame` by the inventor.

Certain plant varieties of the Cactaceae family are well known in the foliage plant market and among these are those which are commonly referred to as the Christmas Cactus varieties because they tend to bloom during the Thanksgiving-Christmas holiday season.

The Christmas Cactus varieties on the market have blooms which vary in color from one variety to the next as is evident from the current U.S. patent art. However, the only Christmas Cactus variety known to the inventors and which has a generally "yellow" colored bloom is the "Gold Charm" variety which forms the subject matter of U.S. Plant Pat. No. 5,104.

A general objective has been to develop a new plant variety which is distinguishable from the "Gold Charm" variety and which is capable of being marketed competitively therewith.

SUMMARY OF THE INVENTION

The new plant variety was developed in a nursery located at Winter Garden, Fla., from a natural mutation that appeared on a specimen of the "Gold Charm" variety which was under cultivation at the nursery.

Through successive propagations of cuttings taken from the mutated plant part, it has been ascertained that specimens of the new plant variety generally resemble the "Gold Charm" variety in most respects but are distinguishable from this variety and from other related varieties known to the inventors by a growth habit which is evident in plant specimens of the new variety which have been propagated and grown under nursery conditions utilized in the growing of tropical plants in Winter Garden, Fla., as combining the following principal characteristics:

1. An erect growth habit,

2. Buds with (a) an ovary having a basic field during immaturity in which the color is usually dominated by a red hue, and in which, with further maturity of the bud, there is a development of random areas in which the color is dominated by a yellow green hue, and (b) petals having a basic field during bud immaturity in which the color is usually dominated by a red and/or pink hue and in which, with further maturity of the bud, there is a development of streaks in which the color is dominated by a yellow green and/or olive green hue, and

3. Sterile flowers having tepals with (a) a narrow marginal blade area that in color is dominated by a reddish orange, orange, orange yellow and/or pink hue, and (b) a center blade area that in color is dominated by a yellow hue and merges distally with the color in the basal area of the tepal blade.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings serve by color photographic means to illustrate the new plant variety and wherein one sheet shows a ten (10) month old specimen which was grown from the propagation of a single phylloclade in a conventional 3" pot found in the marketplace. A second sheet shows an enlargement of a fully open bloom taken from the specimen shown in the photograph of the previously mentioned sheet. Still another sheet shows a bloom as sectioned generally longitudinally through the perianth tube and ovary to expose the style and stamen arrangement. The last sheet shows two horizontal rows of phylloclades that bear buds in various stages of development, the phylloclades in the bottom row having been taken from specimens of the new plant variety while the phylloclades in the top row were taken from a specimen of the "Gold Charm" variety and are shown to provide comparison.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new plant variety with colors and hues, unless otherwise clearly indicated by the text as, for example, through the absence of color notations, being named in accord with the ISCC-NBS Method of Designating Colors (U.S. Dept. of Commerce, National Bureau of Standards, Circular 553), the named colors being interpreted from color notations derived by comparison with the color specimens of the Munsell Book of Color. The description is further based on observations of well fertilized plants of about one year of age from initial propagation which were grown under 50-75% shaded glasshouse nursery conditions in the Winter Garden, Fla. area and wherein temperatures range from 60°-85° F. during the winter months, from 75°-95° F. during the summer months, and are ambient during the intervening periods.

We claim:
 1. A new and distinct plant variety of the Cactaceae family as shown and described and which is mainly distinguished from its antecedents and known related varieties by a growth habit which is substantially like that of the "Gold Charm" variety but as modified by the combination of the following characteristics:(1) An erect growth habit, (2) Buds with (a) an ovary having a basic field during immaturity in which the color is usually dominated by a red hue, and in which, with further maturity of the bud, there is a development of random areas in which the color is dominated by a yellow green hue, and (b) petals having a basic field during bud immaturity in which the color is usually dominated by a red and/or pink hue and in which, with further maturity of the bud, there is a development of streaks in which the color is dominated by a yellow green and/or olive green hue, and (3) Sterile flowers having tepals with (a) a narrow marginal blade area that in color is dominated by a reddish orange, orange, orange yellow and/or pink hue, and (b) a center blade area that in color is dominated by a yellow hue and merges distally with the color in the basal area of the tepal blade.
